Abstract

The utility model relates to a parallel flow evaporator which is characterized in that a plurality of thin-wall flat pipes are communicated between a left flow collecting chamber body and a right flow collecting chamber body, wherein, the two flow collecting chamber bodies are mutually opposite and the thin-wall flat pipes are mutually parallel. The right flow collecting chamber body is divided into an air discharging chamber and a liquid inlet chamber by a baffle, wherein, the air discharging chamber and the liquid inlet chamber are respectively provided with an air discharging pipe and a liquid inlet pipe. The utility model has the advantages of simple structure, convenient manufacture, low cost, light weight, etc. The resistance of refrigerant can be obviously reduced in a flowing process. The side pressure loss of the refrigerant is little, and thus, heat exchanging efficiency is obviously increased. The utility model can be used for cars, miniature cars, medium-sized buses, minibuses, etc.

Description

Parallel-flow evaporator

The utility model relates to the aircondition in a kind of automobile, the roof-packed evaporator in particularly a kind of passenger vehicle.

Car air-conditioner evaporimeter at present commonly used is divided into pipe type, corrugated tube type, stacked three types.For pipe type car air-conditioner evaporimeter, because its cold-producing medium turns to elbow more, cause the flow of refrigerant resistance bigger, the refrigerant side pressure loss is big; Make its heat-transfer effect bad because of being to dilate to be connected between heat-exchange fin and the conduit; And, conduit make entire product comparatively heavy because of adopting copper pipe usually.For corrugated tube type car air-conditioner evaporimeter and since it be with a flat tube of growing through being processed into snakelike shape, refrigerant flowpath is long, the turning point flexure plane is many, causes the flow of refrigerant resistance bigger, refrigerant pressure loss is big; And make that because of the flat tube wall is too thick its heat exchanger effectiveness is lower.For stacked car air-conditioner evaporimeter, because the limitation of appearance and size, it can not satisfy the condition of big heat exchange amount, and the scope of application is little.

The purpose of this utility model just provides a kind of simple in structure, in light weight, applied widely, parallel-flow evaporator that heat exchanger effectiveness is high.

The purpose of this utility model is to realize by such technical scheme, it is to be communicated with a plurality of thin-walled flat tubes parallel to each other between two left and right afflux cavitys respect to one another, is respectively arranged with gland steam exhauster, feed tube on steam discharge chamber that right afflux cavity is separated into by dividing plate and the admission chamber.

The utility model is work like this: from the low temperature of feed tube inflow, behind the influent stream chamber of the atomized refrigerant of low pressure in right afflux cavity along flowing in one group of thin-walled flat tube parallel to each other, blow over the outer hot-air of thin-walled flat tube by the thin-walled flat tube tube wall and cold-producing medium generation heat exchange after become cold air, cold-producing medium also constantly absorbs heat and flashes to steam state, the cold-producing medium that is steam state is through another group thin-walled flat tube parallel to each other, discharge along gland steam exhauster in steam discharge chamber in the right afflux cavity, become vaporific cold-producing medium after treatment and flow back to again in the feed tube, so circulate the purpose that reaches air cooling repeatedly.Because it is few, big with the contact-making surface of thin-walled flat tube that cold-producing medium is short at flow path of the present utility model, the flow direction is turned, therefore, the resistance that cold-producing medium is subjected in flow process is very little, and its lateral pressure loss is little, significantly improve with the heat exchanger effectiveness in the external world, improved refrigerating efficiency.

Owing to adopted technique scheme, the utlity model has following advantage:

1. simple in structure, easily manufactured, with low cost;

2. because cold-producing medium mode with one group of PARALLEL FLOW in the thin-walled flat tube is carried out, and flow path is short, turn to outer nothing crooked, so the resistance that cold-producing medium is subjected in flow process is little, the lateral pressure loss of cold-producing medium is little.

3. after having adopted the thin-walled flat tube, the one, obviously alleviate the weight of product, the 2nd, increased the contact-making surface between cold-producing medium and the catheter wall, improved heat exchange performance significantly.

4. can be used for car, minicar, minibus and minibus etc., applied widely.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the right view of Fig. 1;

The utility model is described in further detail below in conjunction with drawings and Examples:

Shown in Fig. 1,2,3,4, the utility model is to be communicated with a plurality of thin-walled flat tubes 3 parallel to each other between two left manifolds 1 respect to one another, right afflux cavity 2, is respectively arranged with gland steam exhauster 5, feed tube 6 on steam discharge chamber that right afflux cavity 2 is separated into by dividing plate 4 and the admission chamber.

Shown in Fig. 1,4, in order to strengthen heat exchanger effectiveness, thin-walled flat tube 3 outer walls are provided with fin 7.In order to prevent to sustain damage or be stained with dust, on and under thin-walled flat tube 3 be provided with and fin 7 corresponding anti-edge plates 8.
